Condenser imagwira ntchito podutsa mpweya kudzera mu chubu lalitali (nthawi zambiri limakulungidwa mu solenoid), zomwe zimapangitsa kuti kutentha kutulukire mumlengalenga wozungulira. Zitsulo monga mkuwa zimatenthetsa bwino ndipo nthawi zambiri zimagwiritsidwa ntchito ponyamula nthunzi. Pofuna kupititsa patsogolo mphamvu ya condenser, matenthedwe otenthetsera omwe ali ndi kutentha kwabwino kwambiri nthawi zambiri amawonjezedwa ku mapaipi kuti awonjezere kutentha kwa kutentha kuti apititse patsogolo kutentha, ndipo kutulutsa mpweya kumafulumizitsa ndi fani kuti ichotse kutentha. Mfundo ya firiji ya firiji wamba ndikuti compressor imakanikiza sing'anga yogwira ntchito kuchokera kutentha pang'ono ndi mpweya wocheperako kupita ku kutentha kwambiri komanso mpweya wothamanga kwambiri, kenako ndikulowa kutentha kwapakati ndi madzi othamanga kwambiri kudzera mu condenser. Pambuyo valavu throttle ndi throttled, amakhala otsika kutentha ndi otsika kuthamanga madzi. The otsika kutentha ndi otsika kuthamanga madzi ntchito sing'anga amatumizidwa kwa evaporator, kumene evaporator amatenga kutentha ndi nthunzi mu otsika kutentha ndi otsika nthunzi nthunzi, amene amatengedwa kwa kompresa kachiwiri, motero kumaliza firiji kuzungulira. Dongosolo la refrigeration lagawo limodzi la nthunzi limapangidwa ndi zinthu zinayi zofunika: kompresa ya refrigeration, condenser, throttle valve ndi evaporator. Amalumikizidwa motsatizana ndi mapaipi kuti apange dongosolo lotsekedwa. Refrigerant imazungulira nthawi zonse mu dongosolo, imasintha dziko lake ndikusinthanitsa kutentha ndi dziko lakunja
